5970p or Grand Lange 1 Lumen for the future collection?

[tenerific]

I'm starting to ponder my collection and where I want to go post Rolex (besides my one temporary foray into Datograph territory) and am contemplating two watches for the future.

I know the ideal scenario is why choose / choose both, but curious which of these people think is more appealing and why. I have not seen either in the flesh unfortunately.

The Patek 5970p or Grand Lange 1 Lumen?
